To (4% w from it may concern:

Bait known that l, W ILLIAM Wank, a subject of the King of Great Britain and Ireland, and resident of Buckton Vale,in the county of Chester, England, have invented certain new and useful Improvements Relating to the Production of Patterns or Ornamental Effectsupon Fabrics,"

of which the following is a SPGGlllCitillOll.

This invention relates to the production of patterns or ornamental effects upon fabrics and more particularly cotton fabrics. and has for its object to provide a new and improved pr ccss whereby ornamental effects, which may resemble those resulting from pattern weaving and (or) printing can be obtained in a simple,economical and effective manner.

By investigation and experiment, I have found that if cotton fabrics when in a damp or wet condition be subjected to combined friction or rubbing and pressure by means, which, if the fabric were plastic would produce any desired pattern or ornamentation on the same, then during a subsequent dyeing operation, the said pattern or ornamentation will stand out in a deeper shade than the body of the fabric, due to the appar ently greater aflinity of the frictioned or rubbed portion of the fabric for the dyestuif. Or if the sheet of warp threads prior to being; woven into a fabric, be subjected to combined friction and pressure, the fabric produced being then dyed as aforesaid, a similar ornamentation which resembles a woven pattern results.

The invention comprises the production of ornamental patterns upon a fabric by subjecting portions of the latter or of the warp threads used in its manufacture whilst the fabric or threar'ls is or are in a damp or wet coiulition, to combined friction or.

rubbing and pressure and fabric. i

In one C(il'l'YQlliQllt app]ioation of the iu-- 'vention, the fabric either before or after bleaching-and Whilst still in a damp or wet then dyeing: the

wonthtion or after damping or wetting, is

passed between a roller or cylinder and what 1 term a frict on device. The latter mayconsist of a cylindrical or other element havin iro"ections thereon so that the surlace ronsists o'l alter-Tinting ridges and grooves. The friction device is pressed against the fabric through lover or other actor or kind Application filed April 11, 1921. Serial No. 460,441.

mechanism or directly by hydraulic pressure and as the fabric is drawn thereover rubsthe latter in a plurality of parallel lines.

When the fabricis subsequently dyed in the ordinary manner, it is found that the rubbed or frictioned parts dye a deeper shade than the remainder of the fabric, so

. producing an ornamental pattern which re:

senibles one produced by printing upon a dyed fabric. i

In some cases, the roller over which the fabric passes may have a pattern produced or engraved therein in relief. The said roller has the same surface speed as the fabric, and a smooth plate, cylinder or the like is pressed against the outer side of the fabric and causes a rubbing action between the fabric and the engraved or ornamental roller so as toproduce in a subsequent dyeing process. the required patterns in a deeper shade than the remainder of the fabric. Or the fabric may be operated upon at both sides in successive treatments.

Beamed warps may be subjected tomy improved frictioniing; process, if desired, before being woven into a fabric, the latter being then dyed as before described.

I do not limit myself to any particular means for rubbing the fabric or threads for producing the desired ornamentation, but may vary the same to suit any particular services or requirements.

The "pattern produced in the dyed fabric may appear on one or both sides of the latter according to the degree of pressure applied thereto during the l'llbbll'lg' operation.

Afabric ornamented as before described, may have its appearance varied by the charof weaving employed in producinp; the fabric. in some cases. the cf fer-ts resulting from my iu'iprorcd process resemble woven patterns.

If my improved process is to be used upon memorized goods. the latter must be washed and dried after mercei'imtiou,.and then be damped or wetted before the frictioning operation before described. The. frictioned parts will then dye darker than the body of the fabric and lose some or all of their lustre. i i

Having now described my invention what I claim as new and desire to secure by Letters Patent is: i

l. The process of preparing textile niatcriahii for dyeing consisting in subjecting combined friction or rubbing and pressure, and subsequently dyeing the fabric, as set forth. 10

In testimon whereof I have signed my name to this specification.
